Thread the reconciler's existing isRemount signal into MounterArgs so
volume plugins can distinguish an initial publish from a republish
(e.g. CSIDriver.spec.requiresRepublish=true). No behavior change.
Automated cherry pick of #131950: PodStartSLIDuration should exclude init container runtime, image pulling time, stateful pods, not immediately schedulable pods
FetchInitConfigurationFromCluster always called SetAPIEndpointDynamicDefaults,
which invokes ChooseAPIServerBindAddress and requires a default route on the
host. Worker nodes joining the cluster don't need a LocalAPIEndpoint and may
legitimately have no default route, causing kubeadm join to fail with:
```
unable to fetch the kubeadm-config ConfigMap: unable to select an IP from
default routes.
```
Add a skipAPIEndpoint parameter to SetInitDynamicDefaults and pass
`!getAPIEndpoint` from FetchInitConfigurationFromCluster, so the endpoint
defaulter is bypassed when the caller did not request the endpoint (worker
join, non-control-plane reset/certs/upgrade paths).

Historicaly the kubeadm clients have used the 'admin.conf'
and 'super-admin.conf' directly, which makes all API calls
go trough the CPE (control plane endpoint). This can create
problems for scenarios when the LB is provisioned only after
'init' starts the kube-apiserver.
Instead of using the '.conf' as they are, modify them
in memory to point to the LAE (localAPIEndpoint).
This was already done by the WaitControlPlaneClient for
the WaitControlPlane phase, which required it. This separate
client is no longer needed.
However, do use a unmodified kubeconfig to the init phase
bootstrap-token since this is the phase that creates
the cluster-info CM and for that we need the original CPE
server address.
Periodic full-syncs are just reconcile loops just in case somehow
the dataplane has drifted, however, they have an important cost on large
clusters.
We can avoid to perform full-sync if kube-proxy is in the "largecluster"
mode, we are already doing some optimization, so it is reasonable to
avoid the penalty of a full sync for a "just in case" operation.

handleSchedulingFailure can refresh podInfo from the informer before AddUnschedulableIfNotPresent. A delete and recreate with the same name may change the Pod UID while inFlightPods still tracks the UID from Pop, so Done and queueing-hint lookups must use that in-flight UID.
Add an explicit in-flight UID parameter, thread it through queueing-hint lookups, cover the same-name recreation case with a regression test, and check the returned error in updated test call sites.
An ipAllocator with a 64 bit IPv6 CIDR can allocate
addresses outside the CIDR range, due to an improper uint64 to int64
cast in the addOffsetAddress function.
Replace the cast with a call to `math/big.Int.SetUint64()`.
Currently the provider that the podresources API
consumes does *not* obviously filters out the terminal
pod, and this is corroborated by the fact the related
e2e test starts to fail.
We had a bug in the test which masked the real failure,
but now it's evident.
So we perform a trivial extraction of the kubelet filtering
code and we apply in both places.
Note that the existing flow is unaffected except for the
trivial code extraciton.

When a container restarts before kubelet restarts, containerMap has
multiple entries (old exited + new running). GetContainerID() may
return the exited container, causing the running check to fail. Fixed
by checking if ANY container for the pod/name is running.
Also filter terminal pods from podresources since they no longer
consume resources, and fix test error handling to avoid exiting
Eventually immediately on transient errors.
